Environment-friendly combustion type garbage cyclic treatment equipment

The invention discloses environment-friendly combustion type garbage circulating treatment equipment, and relates to the technical field of garbage treatment. The internal combustion engine comprises an energy supply box, a transmission frame, a supporting frame and an output crankshaft, the energy supply box, the transmission frame and the output crankshaft form a macroscopic internal combustion engine structure, an evaporation kettle is arranged in the energy supply box, and the evaporation kettle and a transmission cylinder form a microcosmic external combustion engine structure. Through the energy supply box, the transmission frame and the output crankshaft, garbage raw materials are placed in the energy supply box to be combusted to generate heat, then the output crankshaft is driven to rotate and be converted into kinetic energy, the structure of the internal combustion engine is integrally formed, and the recovery rate and the utilization rate of energy in garbage incineration are increased; meanwhile,
